The difference between the length and breadth of a rectangle is 6 metre. The length of rectangle is equal to the side of the square whose area is 729 sq. metre. What is the perimeter of rectangle ? (in metre)
1). 92
2). 108
3). 96
4). 88
Length of rectangle = Side of square
= $\sqrt{729} = 27$ metre
=> Breadth of rectangle = $27 - 6 = 21$ meters
$\therefore$ Perimeter of rectangle
= $2 (27 + 21) = 2 \times 48$
= $96$ metre
Length of rectangle = Side of square
= $\sqrt{729} = 27$ metre
=> Breadth of rectangle = $27 - 6 = 21$ meters
$\therefore$ Perimeter of rectangle
= $2 (27 + 21) = 2 \times 48$
= $96$ metre
